The physiological response of skeletal muscle to repeated, rapid stimulation without time for complete relaxation in between is called:

A. Treppe
B. Muscle tone
C. Incomplete tetanus
✓
D. The stress-relaxation response

📝 Explanation

When a skeletal muscle is stimulated rapidly, the twitches summate. If the stimuli are rapid enough that the muscle only partially relaxes between them, it enters a state of sustained, quivering contraction known as incomplete (or unfused) tetanus.
